I attached a file to better understand my problem. It shows different squares, that represents different floors of the same building. Each color is in a different layer. I inserted a table to fill with the total length of polylines I used in each layer (BLue layer: 50 m, Red layer: 100m) etc. What I usually do is filter the selection by each layer and then run a program I developed that calculates the total length of what I selected, then I copy that value and fill the table with it. I'd like the process of filling it to be more automatic, like a field that calculates a certain property and chances its value accordingly when you modify your drawing. To sum up, I want to fill the table faster once I'm done making the drawing.
I don't know if I made myself any clearer, but I appreciate your message and would be grateful for any insights you might have to share. Please let me know if you didn't understand or if you have any trouble with the file.
Thank you!
